A series of random polyesteramides (PEAs) with a range of molar composition from 90/10 to 50/50 were synthesized by direct melt polycondensation of ε‐caprolactone and l‐alanine. Their structure was fully characterized by Fourier transform IR and NMR spectroscopy. The resulting copolymers are completely amorphous with the exception of PEA‐90/10 which possesses a semicrystalline structure. These PEAs present increasing glass transition temperatures at increasing l‐alanine contents and exhibit fairly good thermal stability with 10% mass loss temperatures reaching 315 °C. © 2020 Society of Industrial Chemistry

直接熔融共聚形成无规聚（ε-己内酯-L-丙氨酸）

通过ε-己内酯和1-丙氨酸的直接熔融缩聚反应，合成了一系列摩尔组成范围为90/10至50/50的无规聚酯酰胺（PEA）。它们的结构通过傅里叶变换红外光谱和核磁共振谱进行了充分表征。除具有半结晶结构的PEA-90 / 10外，所得共聚物是完全无定形的。这些PEA随着l-丙氨酸含量的增加而呈现出越来越高的玻璃化转变温度，并表现出相当好的热稳定性，10％的质量损失温度达到315°C。©2020工业化学学会
